A Technical Overview of the ZX267 High Voltage Withstand Tester

The ZX267 series High Voltage Withstand Tester is a precision instrument designed for dielectric strength testing, commonly known as hipot testing, flash testing, or breakdown testing. It is extensively utilized across various industries to evaluate the electrical insulation integrity of components and products such as transformers, motors, cables, wiring, electrical appliances, meters, and electronic devices. By applying high voltage to a device under test, the ZX267 helps verify that insulation can withstand specified voltage levels without excessive leakage current, ensuring safety and compliance with international standards.

Key Features and Capabilities

The ZX267 tester integrates several user-oriented features that enhance both functionality and operator safety:

1.Digital Display – Provides clear, real-time monitoring of test voltage and leakage current.

2.Leakage Current Measurement – Displays leakage current in multiple ranges, allowing precise monitoring of insulation performance during testing.

3.Programmable Test Timer – Allows setting of test duration with countdown display, supporting both timed and manual test modes.

4.Adjustable Alarm Current – Users can preset leakage current limits; exceeding this threshold triggers an alarm, indicating potential insulation failure.

5.Output Waveform – Generates a 50Hz sine wave AC output, with certain models offering DC output for different testing requirements.

Technical Specifications Across Models

The ZX267 series includes multiple models to accommodate varying test requirements. Below is a summary of key specifications:

General Performance Parameters

1.Voltage & Current Accuracy: ±5%

2.Timer Range: 1–99 seconds (digital) ±5%, plus manual test mode

3.Power Supply: AC 220V ±10%, 50Hz ±2Hz

4.Power Consumption: ≤30 W (static)

Application and Selection Guidance

When selecting a suitable ZX267 model, consider the following:

1.Voltage Requirements: Choose AC or DC output based on the test standard. Models with dual voltage ranges (e.g., 0–5/10 kV) offer greater flexibility.

2.Current Sensitivity: Models with wider leakage current ranges (e.g., up to 200mA AC) are suitable for testing higher-capacity equipment.

3.Output Power: Higher power models (e.g., 1000 VA) are designed for testing larger loads such as cables and transformers.

4.Portability: Smaller units like the ZX2670A are lightweight and ideal for bench use or field service.

Conclusion

The ZX267 High Voltage Withstand Tester series provides reliable, accurate, and safe dielectric strength testing for a wide spectrum of electrical and electronic products. With configurable test parameters, clear digital readouts, and robust construction, it serves as an essential tool for quality assurance, production line testing, and laboratory validation. Technicians are advised to refer to the specific model’s datasheet and relevant safety standards when performing tests to ensure accurate and secure operation.
